macOS Tahoe Beta Performance - Blown Away!

[blipmusic]

it is in index-36seed-1.sucatalog for beta 3

do this in terminal

for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-26seed-1.sucatalog | grep com_apple_MobileAsset_MacSoftwareUpdate.plist | grep -Evw '(com_apple_MobileAsset_MacSoftwareUpdate.plist.integrityDataV1)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g); do
curl -s $file | egrep -A 1 -m 2 '(>Build<|OSVersion)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g | sed -e s/"<key>"//g -e s/"<\/key>"//g -e s/\ //g
echo $file | sed -e "s/com_apple_MobileAsset_MacSoftwareUpdate.plist/InstallAssistant.pkg/g"
done

and u see this

            Build
            25A5306g
--
            OSVersion
            26.0

that's beta 3

Thanks but, "https://swscan.apple.com/content/catalogs/others/index-36seed-1.sucatalog" (or beta-1) was my first thought and curl:ing returns nothing though...?

Your code block uses the previous file index-26seed-1.sucatalog, though. Which works fine and was actually updated on July 7 and now lists two builds, the last being beta 3 build 25A5306g (i.e. need to ensure to pick the last one listed, xml/plist-parsing time at this point perhaps, if Apple keep updating the same sucatalog-file ).

b1 and b1 were crazy slow with all the animations but b3 is like a crazy step up and I think is on par if not better and more fluid then my last Sequoia installation. there are some small quirks like in Safari if you use sdie bar, left top is covering the settings (but only in full screen) but overall I can see they work hard and improve the OS rapidly.

not sure if anyone noticed but dark mode is so much more transparent and glossy (ale the menu bar menus are transparent etc.) , and white is just white mostly, hope white will become more transparent and nicer

Dark theme definitely feels much better. Toolbar buttons in Finder look much better. Too bad I kinda hate dark mode.

How exactly do you just erase the data volume without having to reinstall the OS? Where is this setting? For ages, I've installed on top of previous versions of macOS, and I would like to start clean w/o having to wipe my entire SSD and reinstall when macOS 26 is released later this fall.

This is what I do. Works like a charm. And yes, I wanna get rid of everything to do with the OLD OS when I install a new one. With this method, if in case your USB fails to boot, then you can simply install the OS via Internet recovery. Has happened just once.

Create your bootable USB - Reboot in Recovery Mode. Open Disk utility, select the top level drive icon for the internal ssd on your Mac. elect erase - options pops up to erase Mac - wait for finish - reboot using the USB and install again.

In Safari I still have pages that won't load or partially load. I have experimented with activating the Develop menu in Safari and the best way I can get web pages to load correctly is to use Google Chrome - Windows as the User Agen

This seems practical, iOS-style! So if this deletes or "factory resets" everything on the writable volume, it *should* be the same as a clean install, right?

Yes. It is exactly the same as clean install.

How to ‘clean’ install modern macOS

If you normally ‘clean’ install a new version of macOS, how can or should you do that with Sonoma or another recent version on a modern Mac?

Something I noticed last night was that my external monitor (32" 4K Samsung) suddenly looked significantly better in Beta 3, actually comparable to the built-in display on my MBP. The screen was noticeably sharper and the colors were richer and more saturated. Before Beta 3 and even running Sequoia the 4K display always looked softer and less vivid than the MBP's display. I have not made any changes to the display settings, so it's something in the OS that changed (for the better, IMHO)...

On my touch-bar M1 MBP, Safari, specifically, is causing mild to crazy stutter and lag even in Beta 3. Granted, I had hundreds of tabs open across 12 or so windows, but on Sequoia animations were still smooth (Mission Control, switching virtual desktops etc). I've since reset everything as described above for a clean install. While I'm sure there were problematic sites among all those old tabs causing high CPU, the symptoms are still there with just 10 or so tabs open across 2 windows.

WindowManager CPU was at a minimum of 60% before resetting so perhaps the new glass UI needs more optimisation. CPU loads are now down, similar to what I got in Sequoia.

Otherwise most of what I need, apps and dev tooling, seems to work so far.

Is it me or does it feel sluggish. Everything works fine and usually everyone says Safari feels snappier, but for once to me it feels the opposite.

does everything feel sluggish? how long since you installed the beta... and which mac is this?

here, everything is fast, efficient. and safari is on a site before i can type in the sitename... 😉

 

[owidhh]

Safari won’t even work for me on beta3 as well as iCloud settings… must be something wrong maybe in private relay but I can’t turn it off without functional iCloud settings lol. Other than that performance feels the same as on sequoia

finally a reboot fixed it (didn't fix it the previous 2 reboots, so that's weird, but anyway)

Otherwise, snappy!!!

Safari and animations (Mission Control) are worse in my case. As soon as Safari is open animation, desktop switching etc becomes jittery. I also often get "sticky" scrolling in Safari (don't think I've seen this elsewhere yet) with internal/external trackpad. Corded or bluetooth doesn't make a difference. In Safari it's as if the "scroll momentum" required is suddenly set too high. I.e. the scrolling immediately stops when letting go unless I make more "forceful" gestures. And sometime scrolling works ok, so hopefully just bugs to iron out.

I've been on Beta 3 since it came out...Using Mac Studio M1 Ultra with 128GM RAM. Messages is very sluggish as it literally takes 2 seconds for the window appear even after the window is close but the app is still open.

Safari is very messed up for me. Extremely slow to load anything compared to Firefox or Chrome, and some sites just simply don't load at all. I've resorted to using Firefox and will try Safari again in subsequent betas.

On my M1 MacBook Pro 14" Safari has been good for the most part. Occasionally sites don't load or are slow. Mainly Facebook is the most problematic. Using the Develop Menu and using User Agent Google Chrome-Windows makes these problematic sites load better. I reported this to Apple. I think they'll fix it by the time Golden Master is released!
